Description

Die vorliegende Erfindung betrifft ein Rollensystem für eine ausfahrbare Zustiegsghilfe, insbesondere einen Schiebetritt eines Türeinstiegs eines Personenbeförderungsfahrzeuges, wobei die Zustiegshilfe aus einer Ruhestellung in eine Gebrauchsstellung und zurück verfahrbar ist.The present invention relates to a roller system for an extendable Zustiegsghilfe, in particular a Schiebetritt a door entry of a passenger transport vehicle, wherein the boarding aid from a rest position in a position of use and back is movable.

Derartige Zustiegs- und Zufahrtshilfen werden bei Fahrzeugen zur Personenbeförderung, beispielsweise bei Bussen oder Schienenfahrzeugen des öffentlichen Nahverkehrs eingesetzt. Sie sind in vielfältiger Form bekannt und erleichtern den Ein- und Ausstieg dadurch, dass im Bereich von Haltestellen an den Fahrzeugen verschiebbar und oftmals auch verschwenkbar gelagerte und belastbare Schiebetritte ausgefahren werden. Schiebetritte werden dabei zur Überbrückung von Spalten (beispielsweise bei Bahnsteigen) oder auch zum Höhenausgleich eingesetzt. Zustiegshilfen können als lediglich ausfahrbare Schiebetritte ausgeführt sein, sie können aber im ausgefahrenen Zustand auch auf den Untergrund, beispielsweise dem Bahnsteig abgesenkt werden, so dass sie mit aufliegen. Zustiegshilfen erleichtern oder ermöglichen Rollstuhlfahrern den Zugang in die Fahrzeuge. Nach Beendigung der Aus- und Einstiegsphase und eventuell nach dem Schließen der Fahrzeugtüren wird die Zustiegshilfe wieder in ihre Ruhestellung zurückgebracht.Such approach and access aids are used in vehicles for passenger transport, such as buses or rail vehicles of public transport. They are known in many forms and facilitate entry and exit in that in the area of stops on the vehicles displaced and often also pivotally mounted and resilient sliding steps are extended. Sliding steps are used to bridge gaps (for example on platforms) or for height compensation. Approach aids can be designed as only extendable sliding steps, but they can be lowered in the extended state on the ground, for example, the platform so that they rest with. Boarding aids facilitate or enable wheelchair users to access the vehicles. After completion of the training and entry phase and possibly after closing the vehicle doors the boarding aid is returned to its rest position.

Zustiegshilfen, die im ausgefahrenen Zustand nicht aufliegen und entsprechend belastbar sein müssen, werden in der Regel als Schiebetritte bezeichnet. Diese bestehen in der Regel aus einem widerstandsfähigen und starren, aber möglichst leichten Material und sind in der Regel mit einer rutschhemmenden Auflage versehen.Approach aids, which do not rest in the extended state and must be able to be loaded accordingly, are generally referred to as sliding steps. These are usually made of a resistant and rigid, but as lightweight as possible material and are usually provided with a slip-resistant pad.

Im Bereich des Schiebetritts ist bei fremdbetriebenen Zustiegshilfen ein Motor vorgesehen, der den Schiebetritt aus seiner Ruhestellung in die Gebrauchsstellung heraus- und wieder zurückfährt. Begehbare Schiebetritte sind seitlich über Rollen in Führungsmitteln geführt, über die sie linear ein- und ausgefahren werden können. Motorisch betriebene Schiebetritte sind beispielsweise in den Druckschriften DE 20 2007 000 912 U1 und DE 20 2006 016 432 U1 beschrieben. Diese bauen alle verhältnismäßig hoch, was zunehmend unerwünscht ist. Fahrzeughersteller richten aufgrund ständig wachsender Anforderungen besondere Aufmerksamkeit auf Zustiegshilfen, insbesondere auf den für diesen notwendigen Einbauraum im kritischen Eingangsbereich. Die Einbautiefe und Einbauhöhe ist vom Ausfahrweg, Belastungsweg der Belastung selbst und den Dimensionen vom Führungs- und Rollensystem abhängig.In the area of the sliding step, a motor is provided in the case of externally operated boarding aids, which moves the sliding step out of its rest position into the position of use and back again. Walk-in sliding steps are led laterally over rollers in guide means, over which they can be linearly extended and retracted. Motorized sliding steps are for example in the publications DE 20 2007 000 912 U1 and DE 20 2006 016 432 U1 described. These all build relatively high, which is increasingly undesirable. Vehicle manufacturers pay particular attention due to ever increasing demands on boarding aids, in particular on the necessary installation space in the critical entrance area. The installation depth and installation height depend on the extension path, load path of the load itself and the dimensions of the guide and roller system.

Die Aufgabe der vorliegenden Erfindung besteht darin, ein System für eine Zustiegshilfe, insbesondere einen Schiebetritt zu schaffen, das einen kompakten und Platz sparenden Aufbau der Zustiegshilfe ermöglicht. Weiterhin sollen die o.g. Nachteile des Standes der Technik vermieden werden.The object of the present invention is to provide a system for a boarding aid, in particular a sliding step, which allows a compact and space-saving construction of the boarding aid. Furthermore, the o.g. Disadvantages of the prior art can be avoided.

Erfindungsgemäß wird die Aufgabe durch ein Rollensystem für eine ausfahrbare Zustiegshilfe eines Türeinstiegs eines Personenbeförderungsfahrzeuges gelöst, wobei

  • die Zustiegshilfe aus einer Ruhestellung in eine Gebrauchsstellung und zurück verfahrbar ist,
  • Führungsmittel vorgesehen sind, die jeweils seitlich der Zustiegshilfe in Ein-/Ausfahrrichtung verlaufen und
  • die Zustiegshilfe über Rollen in den Führungsmitteln geführt ist, und dadurch gekennzeichnet ist, dass
    die Zustiegshilfe je Führungsmittel zumindest ein Rollenmodul mit einer Rollenplatte aufweist, die um eine Schwenkachse schwenkbar an der Seite des Schiebetritts gelagert ist und in den mindestens zwei in dem jeweiligen Führungsmittel geführte Modulrollen drehbar gelagert sind.
According to the invention, the object is achieved by a roller system for an extendable boarding aid of a door entry of a passenger transport vehicle, wherein
  • the boarding aid is moved from a rest position into a use position and back,
  • Guide means are provided, each extending laterally of the boarding in the extension / retraction and
  • the boarding aid is guided by rollers in the guide means, and characterized in that
    the boarding aid per guide means has at least one roller module with a roller plate, which is mounted pivotably about a pivot axis on the side of the sliding step and in which at least two guided in the respective guide means module rollers are rotatably mounted.

Das erfindungsgemäße Rollensystem eignet sich für sämtliche rollengeführten Zustiegshilfen, insbesondere aber für Schiebtritte. Schiebetritte müssen deshalb, weil sie nicht auf dem Untergrund aufliegen, derart stabil konstruiert sein, dass mehrere Personen gleichzeitig den Schiebetritt betreten können, ohne das dieser nach unten nachgibt oder Schaden nimmt. Dementsprechend sind insbesondere die begehbare Platte des Schiebetritts, die Führungsmittel und die darin laufenden Rollen durch Materialauswahl und Dimensionierung entsprechend ausgeführt. Insbesondere müssen die Rollen in der Lage sein, der auftretenden Belastung Stand zu halten.The roller system according to the invention is suitable for all roll-guided boarding aids, but especially for sliding steps. Sliding steps therefore, because they do not rest on the ground, must be so stably constructed that several people can enter the sliding door at the same time, without this yields down or takes damage. Accordingly, in particular, the walk-in plate of the sliding step, the guide means and the rollers running therein are designed according to material selection and dimensioning. In particular, the rollers must be able to withstand the load occurring.

Hier setzt die Erfindung an, nämlich durch Abkehr vom üblichen und weit verbreiteten Rollensystem. Das erfindungsgemäße Rollenmodul bewirkt, dass die sonst auf eine Rolle wirkende Belastung gleichmäßig auf mindestens zwei Modulrollen verteilt wird.This is where the invention comes in, namely by turning away from the usual and widespread role system. The roller module according to the invention causes the otherwise load acting on a roll is evenly distributed on at least two module rolls.

Die Rollenplatte ist schwenkbar an der Seite Zustiegshilfe gelagert und hat dadurch eine Art Wippenfunktion. In einer besonders vorteilhaften Ausführungsvariante sind zwei Modulrollen vorgesehen, die gleichmäßig beabstandet rechts und links der Schwenkachse der Rollenplatte angeordnet sind. Somit wird die Belastung durch eine von oben wirkende Vertikalkraft über die Platte des Schiebetritts auf das Lager der Rollenplatte und schließlich auf die beiden Rollen selbst übertragen. Bei einem derartigen Rollenmodul halbiert sich die auf die einzelne Modulrollen wirkende Kraft gegenüber der Verwendung nur einer einzigen Rolle.The roller plate is pivotally mounted on the side entry aid and thus has a kind of rocker function. In a particularly advantageous embodiment, two module rollers are provided, which are arranged equally spaced right and left of the pivot axis of the roller plate. Thus, the load is transferred by a vertical force acting from above over the plate of the sliding step on the bearing of the roller plate and finally on the two rollers themselves. With such a roller module, the force acting on the individual module rollers is halved compared with the use of only a single roller.

Erfindungsgemäß kann vorgesehen sein, dass das Rollenmodul nicht zwei, sondern drei oder mehrere Modulrollen aufweist. Zum einen können die Rollen gleichmäßig entlang der Rollenplatte verteilt angeordnet sein, so dass sie jeweils die gleiche Last abtragen, denkbar ist aber auch eine Verteilung, bei der einzelne Rollen mehr oder weniger als andere belastet werden. Dies kann beispielsweise dadurch erreicht werden, dass die Rollen unterschiedliche Abstände zur Schwenkachse aufweisen oder rechts und links der Schwenkachse eine unterschiedliche Anzahl an Modulrollen angeordnet ist.According to the invention, it can be provided that the roller module has not two, but three or more module rollers. On the one hand, the rollers can be arranged distributed uniformly along the roller plate, so that they each remove the same load, but it is also conceivable a distribution in which individual roles are more or less burdened than others. This can for example be achieved in that the rollers have different distances to the pivot axis or right and left of the pivot axis a different number of module rollers is arranged.

Üblicherweise ist ein Schiebetritt nach dem Stand der Technik durch jeweils zwei beabstandete Rollen in dem entsprechenden Führungsmittel geführt. Erfindungsgemäß kann vorgesehen sein, dass die in Ausfahrrichtung vordere Rolle durch ein Rollenmodul ersetzt wird, denkbar ist selbstverständlich aber auch ein Austausch sämtlicher Rollen durch Rollenmodule. Die Anzahl einzelner Rollen und Rollenmodule ist im Wesentlichen von der Dimension und den zu erwartenden Belastungen der Zustiegshilfe bzw. des Schiebetritts abhängig und kann entsprechend frei gewählt werden.Typically, a prior art sliding tread is guided by respective two spaced rollers in the respective guide means. According to the invention, it may be provided that the front roller in the extension direction is replaced by a roller module, but of course also an exchange of all rollers by roller modules is conceivable. The number of individual rollers and roller modules is essentially dependent on the dimension and the expected loads on the boarding aid or the sliding step and can be freely selected accordingly.

Das erfindungsgemäße Rollensystem erlaubt eine Reduzierung der Höhe der Zustiegshilfe insbesondere dadurch, dass die Modulrollen einen deutlich geringeren Durchmesser als die sonst üblichen Rollen aufweisen müssen. Dies ergibt sich durch die Verteilung der Belastung auf mehrere Modulrollen. Entsprechend kann der Schiebetritt oder die Trittplatte über sehr niedrig bauende Führungsmittel geführt werden, wodurch die Gesamthöhe der Zustiegshilfe erheblich reduziert wird.The roller system according to the invention allows a reduction in the height of the boarding aid in particular in that the module rollers must have a significantly smaller diameter than the usual roles. This results from the distribution of the load over several module rolls. Accordingly, the Schiebetritt or the tread plate over very low-mounted guide means be guided, whereby the overall height of the boarding aid is significantly reduced.

Der Antrieb des Schiebetritts kann verschieden ausgeführt sein, z.B. durch seitliche Spindeln, welche neben dem Antrieb ebenfalls die Funktion der Führung übernehmen, oder auch durch einen zentralen Antrieb, welcher zusätzliche (z.B. seitliche) Führungsmittel erfordert. Weitere Antriebsmöglichkeiten sind ebenfalls realisiert, auf diese wird jedoch im Rahmen dieser Patentanmeldung nicht eingegangen.The drive of the sliding step may be different, e.g. by lateral spindles, which in addition to the drive also take over the function of the guide, or by a central drive, which requires additional (for example lateral) guide means. Other drive options are also realized, but this is not discussed in the context of this patent application.

Figur 1 zeigt die wesentlichen Komponenten einer Schiebetrittausfahrvorrichtung 20 mit einem ausgefahrenen Schiebetritt 22. Die Schiebetrittausfahrvorrichtung 20 funktioniert prinzipiell nach Art einer Schublade, die Schiebetritt 22 wird durch eine Öffnung des Gehäuses 24 in dieses ein- oder aus diesem herausgefahren. FIG. 1 shows the essential components of a Schiebetrittausfahrvorrichtung 20 with an extended sliding step 22. The Schiebetrittausfahrvorrichtung 20 works in principle like a drawer, the Schiebetritt 22 is moved through an opening of the housing 24 in this or out of this.

Im gezeigten Ausführungsbeispiel sind die in Ein- Ausfahrrichtung verlaufenden Seitenteile des Gehäuses 24 als Führungsmittel 26 ausgeführt, in denen seitlich an dem Schiebetritt 22 angeordnete Rollen 28 geführt sind. Bei der gezeigten Schiebetrittausfahrvorrichtung 20 sind an jeder Seite zwei Rollen 28 vorgesehen. Wie insbesondere Figur 2 zeigt, werden diese Rollen bei einer Belastung des Schiebetritts 22 mit einer entsprechenden resultierenden Kraft Fn und Fv beaufschlagt, wobei die in Ausfahrrichtung vordere Rolle 28 etwa doppelt so stark wie die hintere Rolle 28 belastet wird.In the exemplary embodiment shown, the side parts of the housing 24 which extend in the extension direction are designed as guide means 26 in which rollers 28 arranged laterally on the sliding step 22 are guided. At the shown Schiebetrittausfahrvorrichtung 20 two rollers 28 are provided on each side. In particular FIG. 2 shows, these rollers are subjected to a load of the sliding step 22 with a corresponding resultant force Fn and Fv, wherein the front in the extension direction roller 28 is about twice as much as the rear roller 28 is charged.

Der Schiebetritt 22 weist eine Platte 30 auf, die zwischen zwei parallel zu den Führungsmitteln 26 verlaufenden Seitenwangen 32 angeordnet ist. Die Seitenwangen 32 wirken sozusagen als Haltearme. Die Seitenwangen 32 bzw. Haltearme sind über eine zusätzliche Querverstrebung 34 miteinander verbunden.The sliding step 22 has a plate 30 which is arranged between two parallel to the guide means 26 extending side cheeks 32. The side cheeks 32 act as a kind of retaining arms. The side cheeks 32 and retaining arms are connected to each other via an additional cross brace 34.

Weiterhin ist ein Antrieb 36 im in Ein- /Ausfahrrichtung hinteren Bereich der Schiebetrittausfahrvorrichtung 20 gezeigt.Furthermore, a drive 36 is shown in the rearward in the extension / extension direction of the Schiebetrittausfahrvorrichtung 20.

Die nachfolgenden Figuren verdeutlichen das erfindungsgemäße Rollensystem, wobei die erfindungsgemäße Schiebetrittausfahrvorrichtung 20 im Wesentlichen entsprechend der Schiebetrittausfahrvorrichtung 20 nach dem Stand der Technik aufgebaut ist. Deshalb beziehen sich die grundsätzlichen Erläuterungen zu den Bauteilen der Schiebetrittausfahrvorrichtung 20 nach dem Stand der Technik auch auf die Schiebetrittausfahrvorrichtung 20 mit einem erfindungsgemäßen Rollensystem. Dies wird insbesondere aus Figur 3 deutlich, bei der zwar nicht sämtliche Bauteile gezeigt sind (z.B. keinen Antrieb 36), die aber der Schiebetrittausfahrvorrichtung 20 nach dem Stand der Technik im Wesentlichen gleicht.The following figures illustrate the roller system according to the invention, wherein the Schiebetrittausfahrvorrichtung invention 20 is constructed substantially according to the Schiebetrittausfahrvorrichtung 20 according to the prior art. Therefore, the basic explanations regarding the components of the prior art Schiebetrittausfahrvorrichtung 20 also refer to the Schiebetrittausfahrvorrichtung 20 with a roller system according to the invention. This is especially true FIG. 3 clearly, in which, although not all components are shown (eg, no drive 36), but the Schiebetrittausfahrvorrichtung 20 according to the prior art is substantially similar.

Als wesentlicher Unterschied ist erkennbar, dass die bei der Schiebetrittausfahrvorrichtung 20 vordere Rolle 28 durch ein erfindungsgemäßes Rollenmodul 38 ersetzt ist. Der Aufbau und die Funktion des Rollenmoduls 38 ergibt sich insbesondere aus den Figuren 4 und 5.As an essential difference, it can be seen that the roller 28 at the front in the sliding step extension device 20 has been replaced by a roller module 38 according to the invention. The structure and function of the roller module 38 results in particular from the FIGS. 4 and 5 ,

Das Rollenmodul 38 weist im gezeigten Ausführungsbeispiel zwei Rollen (im Folgenden Modulrollen 40) auf, die in einer Rollenplatte 42 drehbar gelagert sind und jeweils in den Führungsmitteln 34 geführt sind. Die Rollenplatte 42 selbst ist wiederum dreh- oder schwenkbar um eine Schwenkachse X-X seitlich am Schiebetritt 22 gelagert. Somit wird die sonst auf die nur eine vordere Rolle 28 wirkende vertikale Kraft Fv gleichmäßig auf zwei Modulrollen 40 verteilt, was gerade bei der in Ein- Ausfahrrichtung vorderen Rollenlagerung aufgrund der dort höheren Belastung von Vorteil ist. Die gleichmäßige Belastung der Modulrollen 40 ergibt sich dadurch, dass diese jeweils den gleichen Abstand zur Schwenkachse X-X aufweisen.In the exemplary embodiment shown, the roller module 38 has two rollers (in the following module rollers 40) which are rotatably mounted in a roller plate 42 and are each guided in the guide means 34. The roller plate 42 itself is in turn rotatably or pivotally mounted about a pivot axis XX laterally on the sliding step 22. Thus, the otherwise acting on the only one front roller 28 vertical force Fv is evenly distributed on two module rollers 40, which is just in the front in one-extension direction roller bearing due to the higher there Load is beneficial. The uniform loading of the module rollers 40 results from the fact that they each have the same distance from the pivot axis XX.

Im gezeigten Ausführungsbeispiel sind die hintere Rolle 28 und das vorne angeordnete Rollenmodul 38 jeweils an der entsprechenden Seitenwange 32 des Schiebetritts 22 angeordnet.In the embodiment shown, the rear roller 28 and the front arranged roller module 38 are each arranged on the corresponding side wall 32 of the sliding step 22.

Das erfindungsgemäße Rollensystem erlaubt aufgrund seiner deutlich günstigeren Lastverteilung eine deutlich kleinere Dimensionierung einer Zustiegshilfe, insbesondere einer Schiebetrittausfahrvorrichtung 20. Wie bereits ausgeführt, eignet sich das Rollensystem für sämtliche ausfahrbaren Zustiegshilfen, wobei die Nutzung mit einem Schiebetritt 22 sicherlich als bevorzugte Ausführungsvariante anzusehen ist. Die Erfindung ist aber nicht auf das gezeigte Ausführungsbeispiel beschränkt.As already stated, the roller system is suitable for all extendable boarding aids, the use of a sliding step 22 is certainly regarded as a preferred embodiment variant is due to its significantly lower load distribution. The invention is not limited to the embodiment shown.

Die erfindungsgemäße Schiebetritteausfahrvorrichtung 20 ist durch ihre in nahezu alle Richtungen schwenkbare Lagerung sehr schnell und einfach zu montieren, die Ansprüche an die Fertigung der Bauteile hinsichtlich ihrer Abmessungen können deutlich niedriger als bei bekannten Schiebetritteausfahrvorrichtungen 20 sein. Der vorhandene Bauraum wird besser ausgenutzt und die Gelenke sind gegenüber Umwelteinflüssen besser geschützt.The Schiebetritteausfahrvorrichtung invention 20 is very fast and easy to mount by their swiveling in almost all directions storage, the demands on the manufacture of the components in terms of their dimensions can be significantly lower than in known Schiebitt drive devices 20. The available space is better utilized and the joints are better protected against environmental influences.
